The first numbers appearing back-to-back in the number pi. The Feynman Point is highlighted in red.

The Feynman Point is a sequence of six nines that start at the 762nd digit in the decimal sequence of pi. It was named after physicist Richard Feynman, who once stated during a lecture he would like to memorize the digits of π until that point, so he could recite them and quip "nine nine nine nine nine nine and so on".
